Roaming
The ability to use a wireless device is able to move from one access point range to another without losing the
connection.
RTS/CTS Threshold Value
It should remain at its default setting of 2,347. A preamble is a signal used to synchronize the transmission
timing between two or more systems. A series of transmission pulses is sent before the data to indicate that
someone is about transmit data. This ensures that systems receiving the information correctly when the data
transmission starts.
Shared Key
It’s when both the sender and recipient share a secret key. Both units use this key for an extended length of
time, sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets until the key
is changed.
Signal Strength
The signal level indicates the strength of the signal as received at the wireless network interface.
SSID (Service Set Identifier)
It’s the unique name shared among all points in a wireless network. The SSID must be identical for all points
in the network. It is case sensitive and must not exceed 32 characters.
WEP (Wired Equivalent Privacy)
A data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard.
The optional cryptographic confidentiality algorithm specified by IEEE 802.11 used to provide data
confidentiality that is subjectively equivalent to the confidentiality of a wired LAN medium that does not
employ cryptographic techniques to enhance privacy.
WPA
Wi-Fi Protected Access, a specification to improve the security level of wireless networks. It uses 802.1x and
EAP to control network access. Temporal Key Integrity Protocol (TKIP) is used to secure data during
transmission.
